How is the graph of y =(x-1)2 - 3 transformed to produce the graph of y = 5(X+4)??
lina2011 [118]

Answer:

<h2>The graph is translated left 5 units, compressed vertically by a factor of 5, and translated up 3 units.</h2>

Step-by-step explanation:

The initial function is

y=(x-1)^{2} -3

The transformed function is

y=5(x+4)^{2}

Notice that the first function represents a parabola with vertex at (1, -3), and the secong function represents a parabola with vertex at (-4, 0). That means the function was shifted three units up and 5 units to the left. Additionally, the function was compressed by a scale factor of 5, because that's the coffecient of the quadratic term.

Therefore, the right answer is the first choice.
